Specification of Letters Patent.

Application flledl August at, rate. aerial n' naaaa.

Be it known that I, BRYSON TON, a citizen of the United States, residingin the city of Detroit, county of Wayne, and State of Michigan, haveinvented certain new and useful Improvements 1n Connectors, of which thefollowing, taken in connection' with the accompanying sheet of drawings,is a full, clear, and concise descri tion thereof.

' y present invention constitutes an improvement upon the'constructionillustrated and described in a copending application heretofore filed byone Frederick Zenker and myself on July 14, 1916, bearing Serial Number109,280.

My invention comprehends new and improved means for efl'ectivelyconnecting a member of thin blade-like construction to a; supportingmember and adapts itself particularly for efi'ectin'g substantialrigidity in.

the movable contacts of a switch construction to insure the maintenancethereof'in perfect alinement withrespect to the coop erating stationarycontacts.

Another object of my invention is to produce a simplified andinexpensive form of connecting device'fo'r associating a plurality ofmovable members to enable them to be' operated in unison.

In the accompanying drawings, I- have illustrated by way of example onepreferable embodiment of the features and principles of my invention, inwhich- Figure 1 is a view in perspective of a twopole single-throwswitch, embodying such preferred form of my invention.

Fig. 2 is a fragmentary enlarged detail of parts of the switchillustrated in Fig. 1.

Fig. 3 is a View in perspective of one of the connecting devicesemployedfor fastening the insulating cross-head to the knifebladecontacts.

Referring in detail to the drawings, 1

indicates a base preferably made of porcelain or other insulatingmaterial upon which are mounted the stationary contacts 2 of jaw formand pivoted supports 3 for knifeblade contacts 4:. The switchillustrated being of the two-pole single throw type, a pair ofknife-blade contacts are employed,

these being operablyassociated through the medium of the cross-head 5,which is preferably made of'insulating material and for convenience ofapplication is rectangular in ClOS-SECl10II. In order to operate thekn1feblade contacts in such a way as to apply the operating power in abalanced manner, a crank 6 having an extremity 7 is rovided, whichisreceived within the eye 0 ,the connecting member 8, this connectingmember being preferably located midway between the knife-blade contactsand taking the form of' a screw-eye bolt, which is threaded through andextends beneath the cross-head 5 and retained in place by a nut. Thecrank 6 is pivotally mounted at 9 in one side of a protecting housing 10and at a point substantially in alinexnent with the pivot points 11 ofthe knife-bladecontacts. Moreover, the crank is provided with anexterior arm 12, which extends substantially parallel with and in aplane common to the side of the casing and serves to afford meanswhereby the switch may be manipulated. The

- cross-head 5 islocated across and above the Near the lower extremitiesof these connecting devices are the laterally-extending tangs 15, whichare received in conforming aper .tures provided in the knife-bladecontacts 4 after which the ends of the tangs 15 are rlveted dowh tosecurely fasten the knifeblade contactsthereto. In order to secureincreasing rigidity to this form of connection, the connecting device isprovided with a pair of depending lugs or projections 16, p

which bear against theinner sides of the knife-blade contacts. The tang13 is of less width than the greatest width of the device,

tangs 13 of the connecting dethus providing the shoulders 13, which fitagainst and beneath the cross-head, so as to afford increasing rigidityto the connection. It will be observed that the connecting device isformed from a single stamping of sheet metal, making an inexpensiveswitch art which forms a substantial connection etween the cross-headand the knife-blade contacts.

While I have illustrated and described one preferable structure in whichmy invention may find embodiment, I do so by Way of example only aschanges may be resorted to without departing from the spirit and scopeof my invention as defined by the followv ing claims.

metal connector having fastening lugs extending through the cross headand riveted thereover, and fastening lugs extending at right anglesthereto extending through the parts to be connected and having the endsriveted thereover.

2. A connecting device embracing a cross head made of insulatingmaterial and having its extremities extending beyond the outer edges ofparts to be connected and connecting devices connecting the cross headto the parts to be connected, each connecting device comprising a sheetmetal plate hav ing a tang extending through the cross head "receivedWithin anaperture of a part to be connected and to be riveted thereover,a laterally-extending tang substantially Width with said first-mentionedtang and adapted to be received in an aperture provided Within anotherpart to be connected and adapted to be riveted thereover, said lattertang being stamped and bent from the body of the connector at a pointsubstantially in vertical alinement with the said first-mentioned tan".
